The plaque reads:
These rock slabs represent desert sand dune deposits from the Permian Period (245-280 million years ago), and are known as the Lyons Sandstone. This rock formation has produced tracks of pre-dinosaurian, mammal like reptiles, spiders and insects that lived in the desert. These slabs also contain a few of those reptile tracks. They are about the size of the footprint of a small domestic dog. They are the oldest tracks known from eastern Colorado.

Professor of Geology
This display is found at the entrance to the Jefferson County Administration and Courts building. There is ample free parking nearby. The tracks are found on the upper side of the slabs.
